Fuel oil solenoid valves at the burner fronts should be of the manual reset type to __________.

🔍 Key Concepts

• Manual reset vs automatic restart after a power loss • What happens to fuel flow to a burner when electrical power fails and then comes back • Why we must avoid uncontrolled oil accumulation in a furnace for safety

💭 Think About

• Think about what a solenoid valve controlled by electricity does when power is LOST and when power is RESTORED. • Which choice focuses on a hazard that could occur after power comes back on if the valve automatically re-opened? • Which answers are really about normal operator control, and which are about automatic safety in an abnormal condition?

✅ Before You Answer

• Identify when a manual reset would actually be used: during normal operation, or only after a trip/shutdown. • Ask: is the main danger oil entering the furnace while power is off, or when power returns unexpectedly? • Eliminate any choices that just describe something an operator could already do with a regular valve (without a special manual reset feature).
